What you should know to choose a data center OTDR
With the technological evolution occurring in datacenters, test requirements dramatically changed for the ber networks that connect mission-critical servers, networking and storage devices. Selecting the proper OTDR to test your network not only strengthens its reliability, but also improves how quickly and ef ciently the job is done, as well as documenting the quality of […]
Knowledge you should know about 100G Ethernet Transmission
What standard addresses 100G, and when will this standard be complete? The IEEE 802.3ba technical requirements were ratified in the recent April 2010 sponsor ballot. The document has been forwarded for approval to RevCom and is expected to be released in June 2010. When is customer implementation of 100G expected? Early end-user adoption is expected […]
Components of a Data Center
Data centers are comprised of a high speed, high demand networking communication systems capable of handling the traffic for Storage Area Networks (SAN), Network Attached Storage (NAS), file/ application/web server farms, and other components located in the controlled environment. The control of the environment relates to humidity, flood, electrical, temperature, fire controls, and of course, physical access. Communication in […]
FAQ about microQSFP
Q: What will the microQSFP (Micro Quad Small-Form-Factor Pluggable) MSA address and the microQSFP specification define? (Optical interfaces and copper?) A: The microQSFP MSA will develop a specification for a new compact module form factor, microQSFP, and make the specification available to the industry to promote industry adoption of compatible products that can be used […]

Optical Cable Corporation (OCC) announced that it is introducing a new Category 8 RJ45 plug with integral circuit board technology that provides advanced control of crosstalk, return loss and other impediments, “ensuring consistent performance at higher frequencies up to 2000 MHz.” The company continued, “Category 8 Ethernet cable will play a major role in meeting […]
What is ITU-T G.654 Fiber
ITU-T Recommend G.654 fiber is a cut-off shifted single-mode optical fiber especially used for high bandwidth long distance transmission. The G. 654 fiber is a single mode optical fiber and cable which has the zero-dispersion wavelengths around 1300nm, the fiber with loss minimized and cut-off wavelength shifted at around 1550nm. the fiber standard was firstly […]
Time to migrating to 40G/100G
Data growth. The world revolves around digital data. We now rely on data to conduct business, engage in social activities and manage our lives. There is no sign of slowed growth in the production of, and demand for, more data – as well as faster access to it. According to the 2014 IDC Digital Universe […]
24 Fiber MPO-LC Module Cassettes
A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and various security devices. Large data centers are industrial scale operations using as much electricity as […]
FCC Comments Urge Allocation of Spectrum Above 24 GHz for 5G And More
As evidenced by comments to the FCC’s inquiry on the use of spectrum above 24 GHz, there’s a lot of interest in this spectrum from just about every segment of the communications industry—except from broadcast and public safety/land mobile representatives. Originally it was thought this spectrum would not be suitable to reach indoor devices. If […]
